call to SimpleStorage.people errored: Error encoding arguments: Error: invalid BigNumber string (argument="value" value="" code=INVALID_ARGUMENT version=bignumber/5.5.0)
Thank you anyone for their time.
pragma solidity ^0.6.0;
contract SimpleStorage {
// 0 is fav number.
uint256 favoriteNumber;
bool favoriteBool;
struct People {
uint256 favoriteNumber;
string name;
}
People[] public people;
function store(uint256 _favoriteNumber) public {
favoriteNumber = _favoriteNumber;
}
function retrieve() public view returns(uint256) {
return favoriteNumber;
}
function addPerson(string memory _name, uint256 _favoriteNumber) public{
people.push(People(_favoriteNumber, _name));
}
}
People is an array, so you need to specify the index of the array first.
So if you want to access the first person, you have to specify 0 (index begins with 0) in the input box next to the person button.

I thibk the error is occurring because the contract "ERC721Burnable" is trying to inherit from two other contracts "Context" and "ERC721", but "Context" is not defined in the code you provided. So, the definition of a base contract must precede the definition of a derived contract.
How can I make sure that the definition of the "Context" contract is included before the definition of the "ERC721Burnable" contract. Additionally, How can I make sure that "Context" is defined in the same file or imported from a different file.
Bellow is the code

I'm trying to group everything in a flattened contract to have the complete ABI
from solidity:
contracts/3_Ballot.sol:33:37: TypeError: Named argument does not match function declaration.
Request memory newRequest = Request({
^ (Relevant source part starts here and spans across multiple lines).
I get this error every time. What should i do for the solve it?
pragma solidity ^0.4.17;
contract Campaign {
struct Request {
string description;
uint value;
address recipient;
bool complete;
}
Request[] public requests;
address public manager;
uint public minimumContirbution;
address[] public approvers;
modifier restricted() {
require (msg.sender == manager);
_;
}
function Campaign (uint minimum) public {
manager = msg.sender;
minimumContirbution = minimum;
}
function contribute () public payable {
require(msg.value > minimumContirbution);
approvers.push(msg.sender);
}
function createRequest(string description, uint value, address recipient) restricted public {
Request memory newRequest = Request({
description: description,
value: value,
restricted: restricted,
complete: false
});
requests.push(newRequest);
}
}
You can define the Request struct in this way and push it into requests array:
function createRequest(string description, uint value, address recipient) restricted public {
Request memory newRequest = Request(description, value, recipient, false);
requests.push(newRequest);
}
In this way, you can add the struct into your array and can retrieve with all parameters setted previously.
Because you're are using wrong argument(restricted) inside you Request type
try this:
Request memory newRequest = Request({
descritption: descritpion,
value: value,
recipient: recipient,
complete: false
});
I am new in Solidity and currently, I am trying to deploy a simple smart contract that requests ETH price "LOWDAY", and "HIGHDAY". I already did a very similar SC that requests only "VOLUME24HOUR" and it worked great. This is the error that I get:
contracts/API_Consumer_Info.sol:24:66: DeclarationError: Undeclared
identifier. Did you mean "jobID"? Chainlink.Request memory request =
buildChainlinkRequest(jobId, address(this), this.fulfill.selector);
^---^
pragma solidity ^0.6.7;
import "#chainlink/contracts/src/v0.6/ChainlinkClient.sol";
contract APIConsumerInfo is ChainlinkClient
{
uint256 public lowDay;
uint256 public highDay;
address private oracle;
bytes32 private jobID;
uint256 private fee;
constructor() public
{
setPublicChainlinkToken();
oracle = 0x2f90A6D021db21e1B2A077c5a37B3C7E75D15b7e;
jobID = "29fa9aa13bf1468788b7cc4a500a45b8";
fee = 0.1 * 10 ** 18;
}
function requestLowDay() public returns (bytes32 requestID)
{
Chainlink.Request memory request = buildChainlinkRequest(jobId, address(this), this.fulfill.selector); //Error occur here
request.add("get", "https://min-api.cryptocompare.com/data/pricemultifull?fsyms=ETH&tsyms=USD");
request.add("path", "RAW.ETH.USD.LOWDAY");
int timesAmount = 10**2;
request.addInt("times", timesAmount);
return sendChainlinkRequestTo(oracle, request, fee);
}
function fulfill(bytes32 _requestId, uint256 _dayLow) public recordChainlinkFulfillment(_requestId)
{
lowDay = _dayLow;
}
function requestHighDay() public returns (bytes32 requestID)
{
Chainlink.Request memory request = buildChainlinkRequest(jobId, address(this), this.fulfill.selector); //Error occur here
request.add("get", "https://min-api.cryptocompare.com/data/pricemultifull?fsyms=ETH&tsyms=USD");
request.add("path", "RAW.ETH.USD.HIGHDAY");
int timesAmount = 10**2;
request.addInt("times", timesAmount);
return sendChainlinkRequestTo(oracle, request, fee);
}
function fulfill(bytes32 _requestId, uint256 _dayHigh) public recordChainlinkFulfillment(_requestId)
{
highDay = _dayHigh;
}
function withdrawLink() external
{
LinkTokenInterface linkToken = LinkTokenInterface(chainlinkTokenAddress());
require(linkToken.transfer(msg.sender, linkToken.balanceOf(address(this))), "Unable to transfer");
}
}
The base code is not written by my and it works perfectly with "VOLUME24HOUR" call. When I did the necessary changes to request.add("path") and added new variable lowDay/highDay it started to throw error.
Thank you ʕっ•ᴥ•ʔっ
Solidity variable names are case-sensitive.
You have defined a bytes32 property named jobID (uppercase D) but then you're trying to pass jobId (lowercase d).
Solution: Pass the correct case-sensitive variable name. In your case jobID.
I'm starting to approach with Solidity (current version 0.8.0) smart contracts, but I can't understand why the compiler print me an error during the push.
The problem is the following: I'm trying to push an element on array in struct but compile failed with error: Copying of type struct memory[] memory to storage not yet supported.
Here my example:
contract TestNFT is ERC721, Ownable {
struct Child {
string name;
}
struct Father {
string name;
Child[] childs;
}
mapping(uint256 => Child) private _childs;
uint256 nextChild = 0;
mapping(uint256 => Father) private _fathers;
uint256 nextFather = 0;
constructor(string memory name, string memory symbol)
ERC721(name, symbol)
{}
function mint(
string memory name
) public onlyOwner {
_safeMint(msg.sender, nextCharacter);
_childs[nextChild] = Child(name);
nextChild++;
}
function mintFather(string memory name) public onlyOwner {
_safeMint(msg.sender, nextClan);
_fathers[nextFather] = Father(name, new Child[](0));
nextFather++;
}
function insertChildToFather(uint256 fatherId, uint256 childId)
public
onlyOwner
{
Child memory child = _childs[childId];
_fathers[fatherId].childs.push(child);
}
}
How can I fix the insertChildToFather function?
I want to use the mapping find the struct but the mapping just can use the bytes and I need to use the string.
pragma solidity >=0.4.22 <0.6.0;
pragma experimental ABIEncoderV2;
contract land{
address public owner;
constructor() public{
owner = msg.sender;
}
struct Landpaper{
string number;
string landaddress;
string landnumber;
string landpurpose;
uint landgrades;
uint256 landarea;
string holdpoints;
}
mapping(bytes8 => Landpaper) public lp;
modifier Permission(){
require(msg.sender == owner);
_;
}
function set(string memory rfidnumber, Landpaper memory _landpaperRecord) public Permission{
lp[rfidnumber]=_landpaperRecord;
}
function get(string memory rfidnumber) view public returns(Landpaper memory){
return lp[rfidnumber];
}
}
because I have to read the rfid UID and I will translate the UID to string, so I need to use the string set my data. I use the bytes8 and I input string type, I need to change my string to bytes8, plz told me how to do.
You can write a function to convert string to bytes8
function stringToBytes8(string memory sourceStr) private pure returns(bytes8) {
bytes8 temp = 0x0;
assembly {
temp := mload(add(sourceStr, 32))
}
return temp;
}
And call it from set and get functions
function set(string memory rfidnumber, Landpaper memory _landpaperRecord) public Permission {
bytes8 rfidb8 = stringToByte8(rfidnumber);
lp[rfidb8]=_landpaperRecord;
}
function get(string memory rfidnumber) public view returns(Landpaper memory) {
bytes8 rfidb8 = stringToByte8(rfidnumber);
return lp[rfidb8];
}
Though I would suggest to avoid performing conversion process in contract as it would consume unnecessary gas. Instead perform the conversion on client side and pass bytes8 as parameter
function set(bytes8 rfidnumber, Landpaper memory _landpaperRecord) public Permission {
lp[rfidnumber]=_landpaperRecord;
}
function get(bytes8 rfidnumber) public view returns(Landpaper memory) {
return lp[rfidnumber];
}
